Q

What is energy?

A

The ability for something to do work, the motive for every process and function

2
Q

What can energy never do?

A

Be created or destroyed

3
Q

What is an energy transfer?

A

The same type of energy moving

4
Q

What is an energy transform?

A

One type of energy changing into another

7
Q

What type of energy does any object above the ground have?

A

Gravitational potential

8
Q

Name the energy transfer that happens when an object falls

A

Gravitational potential –> kinetic

9
Q

Name three forms of stored energy

A
  • gravitational potential
  • elastic potential
  • chemical
10
Q

What form of energy does a compressed spring have?

A

Elastic potential energy

11
Q

Where does the energy stored in your muscles come from?

A

From the food that you eat

12
Q

Name the main energy transfer and waste energy of a torch

A

Main energy transfer:
Chemical –> light

Waste:
Heat

13
Q

Name the main energy transfer and waste energy of a car

A

Main energy transfer:
Chemical –> kinetic

Waste:
Heat
Sound

14
Q

Name the main energy transfer and waste energy of an alarm clock

A

Main energy transfer:
Electrical (or chemical if it’s battery operated) –> sound (kinetic if old fashioned)

Waste:
Heat

15
Q

Why is the total amount of energy the same before and after an energy transfer?

A

Because energy can’t be created or destroyed

16
Q

What is the conservation of energy?

A

The rule that the energy is the same before and after a transfer

17
Q

What does the conservation of energy rule apply to?

A

All energy transfers

18
Q

What energy transfer does stretching an elastic band cause to happen?

A

Chemical –> elastic potential

19
Q

In terms of energy what happens when you burn a fuel?

A

Chemical energy is transferred to the surroundings, which heat up
